I tried heaps of combinations so I'm not 100% sure what got it working but try the below:
- UEFI Boot (in BIOS)
- Set the motherboard to use iGPU (in BIOS)
- Allow multi monitor support (in BIOS)
- Disable fast boot (in BIOS)
- Install a fresh Windows VM. Don't pass through the AMD GPU. Before you add any drivers, shut the VM down from within the VM and then boot it from Unraid. Then you can add all the drivers etc. I had a copy of the AMD drivers downloaded so I could install the AMD GPU driver first. This stops Windows from trying to install one.
- I bound the GPU to VFIO at Boot
Had my W11 VM up and running for a few days now and everything seems fine. Performance seems great (for my hardware anyway).
